Digital video was designed primarily for capturing real world images, so it is often difficult to capture the thin lines of text legibly. Here are a few tips to consider when you are using text in your video:
• Use larger point sizes (e.g., at least 25 points or more). Larger characters always render better than small ones.
•
• Do not use odd values for the output movie's frame height or width. Always use even numbers. Also, input sources having odd height or width values can result in illegible titles.
• Always generate non-interlaced video (the Lossless preset is the only format that you can specify as interlaced). Interlaced video is much more prone to poor quality text rendering because it may introduce flickering.
